Jobs
Work suits first. Combat partners when the base can run without you watching it.

Rancher
Base work suits
The best first job. You keep the factory alive: fire, water, plants, ore, and wood. Combat legendaries do not chop trees while you are in a dungeon.

Catcher
Exploration and spheres
You fill the palbox with the right work suits and a few fighters. A catcher who only throws at full-HP alphas is how Mega Sphere stacks vanish.

Outrider
Mounts and transport
You move the player and the loot. A flying Pal is how biomes stop being death marches. Do not take the only Nitewing into a dungeon and then wonder why you are walking.

Fighter
Combat party and towers
You clear towers, alphas, dungeons, and raids. Swap Pals the same way you swap weapons. Wrong type into a tower is a wipe, not a DPS check.

Breeder
Eggs, cake, and IVs
Late job. You combine parents for the Pal you wanted and hatch it at the right temperature. Breeding before you have a food belt is how the ranch starves.
